I recently bought an HP laptop (dv7-3085dx) which is supposed to have a pretty good video card (NVIDIA GeForce GT 230M). The card is supposed to output a max resolution of 2560x1600 which is also the max resolution of my monitor.
I've now bought an HDMI to dual link DVI cable - this is after Best Buy's 70 dollar HDMI to DVI (perhaps it was 'single' link?) didn't give me the best resolution.
In Windows 7, when I try to set the max resolution for my 30" monitor, I only get 1280x800, which is absurd. The monitor is great, I love the laptop and the video card supposedly supports such resolutions. I therefore can't figure out why I'm not getting a better resolution.
When I "detect" my monitor in Windows 7, it is shown correctly as a DELL 3007WFP!
